Glass transition as a topological phase transition

open access: yesPhysical Review E, 2022
The glass transition is considered as a phase transition in the system of topologically protected excitations in matter structure. The critical behavior of the system is considered both in statics and dynamics cases. It is shown in the simple model describing the topological defects system in the elastic medium with non-zero shear modulus, most of ...

Disorder induced transitions in resonantly driven Floquet Topological Insulators [PDF]

open access: yes, 2017
We investigate the effects of disorder in Floquet topological insulators (FTIs) occurring in semiconductor quantum wells. Such FTIs are induced by resonantly driving a transition between the valence and conduction band.

Switching between deterministic and accidental Dirac degeneracy by rotating scatterers and the multi-channel topological transport of sound

open access: yesNew Journal of Physics, 2019
In this study, a Dirac cone is yielded at the corner of the Brillouin zone of a two-dimensional solid phononic crystal, which consists of a triangular array of hexagonal steel with a trilobal hole drilled in the center.

Spin and Charge Signatures of Topological Superconductivity in Rashba Nanowires [PDF]

open access: yes, 2017
We consider a Rashba nanowire with proximity gap which can be brought into the topological phase by tuning external magnetic field or chemical potential.

Nonlinear Hall Effects in Strained Twisted Bilayer WSe$_2$

open access: yes, 2020
Recently, it has been pointed out that the twisting of bilayer WSe$_2$ would generate topologically non-trivial flat bands near the Fermi energy.

Topological transitions in metals

open access: yesPhysical Review B, 2019
We investigate if a sharp topological transition in a metal with a large Fermi surface may be detected in transport measurements. In particular, we address if a skew scattering and a side jump on elastic disorder in the bulk of such a metal masks signatures of the topological transition.

Two dimensional Floquet topological states in a driven graphene lattice

open access: yesResults in Physics, 2023
The study of topological phase transitions induced by external fields in quantum systems is of significant interest in physics, as it enables the exploration of various topological nontrivial phenomena in a controllable manner.
